Model: QTSW-0A1X8US
A compact in-wall US Z-Wave relay with potential-free contacts. It requires neutral and a compatible controller. Classic mesh mode can relay other Z-Wave traffic; Long Range uses a separate star connection.

What to know about this device before choosing a connection.
A recommendation is not recorded yet. Compare the requirements below with your home and the capabilities you need.
The manufacturer documents a compact dry-contact relay. Z-Wave schedules or scenes depend on the controller; a device-local scheduler and countdown timer remain unverified. Classic mesh repeating and Long Range star operation are separate inclusion modes. The manufacturer documents a 110–240 V AC, 50/60 Hz device supply and an exact-US OTA firmware resource. Minimum compatible firmware versions, automatic update behavior and applicability to installed firmware remain unverified. The maximum AC contact switching current is 8 A; the separate DC contact limit is 5 A at 30 V DC and does not establish DC device supply. The printed 2000 W at 240 V is not an unqualified wattage rating or a US 120 V load allowance; maximum wattage remains unapproved. Follow the exact unit safety guide and use qualified installation; AC output and DC contact limits are separate from device supply.
Check your ecosystem, then choose a connection method for its requirements and available controls.
A listed ecosystem is a starting point. Connection methods and exposed capabilities must be checked for the exact variant.

Choose a connection method for its app, account and controller requirements. An app used by one method is not necessarily required for every connection.
Device supply is 110–240 V AC, 50/60 Hz, with neutral required for AC operation. The 8 A limit is the maximum AC contact switching current for one output. The separate DC contact limit is 5 A at 30 V DC, not DC device supply; DC powering is not approved by this profile. The printed 2000 W at 240 V is not an unqualified wattage rating or a US 120 V load allowance; no wattage scalar is approved. Follow the exact unit safety guide and use qualified installation. These limits do not establish suitability for every motor/LED load or independent safety certification.
